What does + mean in java
The plus sign ( ) in Java has two uses: arithmetic operator (used to add two numbers) and unary increment operator (used to increment a variable value).
Plus sign ( ) in Java
In Java, there are two types of plus sign ( ) operator Usage:
1. Arithmetic operator
- When used for two numbers, it represents addition operation.
- For example:
int sum = 10 20;
will add 10 and 20 and store the result (30) in thesum
variable.
2. Unary increment operator
- When used for variables, it means to increment the variable value.
- It is a postfix increment operator, which means it returns the value of a variable after incrementing its value.
- For example:
int count = 5; count ;
will increment the value ofcount
from 5 to 6, and then return 6.
Example:
int x = 10; int y = ++x; // y = 11, x = 11 int z = y++; // z = 11, y = 12
Note:
- The increment operator cannot be used for final variables. Because their values cannot be modified.
- The increment operator can be used on Boolean values, which changes the Boolean value from false to true.
